PURPOSE: A lighting opening/closing device and a lighting part thereof are provided to control a distance ratio between a parallel movement and an arc movement by forming the cross point of a link structure in an eccentric location from a center point. CONSTITUTION: A first guide rail(10) is combined with a main frame which has a cover part. A second guide rail(20) is attached to the cover part. A link structure(30) is rotatably combined with one side of the second guide rail and the first guide rail. The link structure is arranged to be mutually connected. Either the first guide rail or the second guide rail is spaced apart from the other by being moved in parallel or in an arc direction. The cross point, in which the link structure is crossed, is located in an eccentric location from a center point. |
